color:#1F497D'>I can’t answer the “checking” question, as I
have never had mine checked, but I “think” I was told they did at
the worlds. As to why the limit on voltage, that’s simply a safety
issue. 40V dc is generally accepted as the threshold for non-lethal
dc voltage. Your skins natural resistance will prevent enough current
from going through you at that voltage to kill you (though as many have
experienced, it can burn the crap out of your fingers). That said,
if you had electrodes poked through the skin, it could still toast you. <o:p></o:p></span></p>

color:#1F497D'>There has been talk about raising that limit to accommodate 12s
batteries which FAI has done for the Heli F3C competitions. I doubt you’ll
see it go above that. I’m actually surprised that the AMA
hasn’t put an upper limit (or maybe they have and I’m unaware) for
the same safety reason.<o:p></o:p></span></p>
